Trivia

In Irish mythology, the Fianna were an elite group of warriors that served the High King of Ireland. The requirements for joining were nothing short of hellish, so being regarded as the "Descendants of Fianna" is true recognition of Orca and Balmung's skills.

A misformatting by Tokyopop seems to indicate Albireo as a third descendant, with the text, "Together with the warrior who wears the eyes of the stars," added to the end of Yeats' poem. In the original Japanese version of the novel, however, it is clear that this is just part of Yeats' signature, hinting at her true identity.
